Only if u kill the user before he does that! :)
But if u are satisfied with filtering what's being pressed you can do
like this (example uses uibinding syntax):
@UiHandler("inputValue")
void onInputValueInserted(KeyUpEvent e) {
if(!inputValue.getText().isEmpty()) {
if(!inputValue.getText().matches("[1-9]\\d{0,}")) { // I want to
filter out what's not a number and those numbers starting with 0
inputValue.setText(inputValue.getText().subSequence(0,
inputValue.getText().length() - 1).toString()); // remove the last
char
}
}
}
